I get the impression from movies (and The Sims) that, in the US, if you want to send a letter you put it in your own letterbox and lift the little flag. Is this correct?


You only have the little flag if your box is on the street, if it's attached to your house as mine is - you can just leave the letter sticking out of the box and they will pick it up while on their route.

I actually knew that about the toilet being walled off from the other bathroom appliances, I believe it saw it on House Hunters International.
